Re:NVIDIA BIOS Editor (NiBiTor) v4.7 software and got feedback? - 2008/12/31 15:14As promised with some delay as you all are aware we have made available a new version of NiBiTor which we hope will lead to some donations. We did get your feedback and some extra BIOS's submitted and with the help of xtremetheme we have a new update to add some extra support. This is a new release which adds extra support for some mobile graphics cards in a better way. Upcoming features or things you would like to see. Let us know and we will see what is possible and/or feasible.
And please provide your feedback, that way we will be able to support you even better! Do let us know what is not working or what you would like to see in any upcoming new version. Also provide your original BIOS as that help a lot to get thing better supported in the next versions!

Re:NVIDIA BIOS Editor (NiBiTor) v4.7 software and got feedback? - 2008/12/31 16:02If you are wondering what is coming with the next version, which is actually ready, we did focus on adding support for several mobile graphics cards. Meaning that we have added almost all those of the GeForce 9M series and that will help I think quite a lot of you but that was quite a lot of work to do so as they had each their own structure of BIOS and well we are still quite disappointed by the low response on the donations. So via this way we do hope that you will start to use the ChipIn button and all those that have done so will get the new version after we received confirmation.
All those that have previously donated will be receiving exclusively the newest version later today as a gift to start the new year. This is because we actually just want to do a one time fund raising but since the response was really so low we just discussed and did release NiBiTor v4.7 though the next version will really be held back until we see some real participation. Also the NiBiTor v4.9 is in the works to add support for the 55nm GT200 products and it also almost ready. So start your ChipIn donations!

Re:NVIDIA BIOS Editor (NiBiTor) v4.7 software and got feedback? - 2008/12/31 21:27I have been testing NiBiTor v4.7 on a HP Pavilion dv6607nr laptop, which is running Windows XP 64-bit. And when I try to load the BIOS backup which I took with PowerStrip it does works well with NiBiTor, except that NiBiTor sees the NVIDIA device as unsupported. When I try to load the BIOS from the machine directly into NiBiTor, the computer crashes and the machine reboots. If I can contribute any other assistance to getting this BIOS supported, I will be glad to help.

And when I try to load the BIOS backup which I took with PowerStrip it does works well with NiBiTor. In fact NiBiTor sees the NVIDIA device as unsupported. Okay I did cut your story short as the info provided was just too much and not really required as we do see this more often with graphics cards where we didn't receive a BIOS of it yet. So first of all you need to take into account you have a chipset the nForce 630M chipset that is actually a chipset that has both the normal system parameters and includes into the same chip the GeForce 7150M graphics device.
And extracting the BIOS from that isn't easy and in fact the BIOS you have uploaded we will have to double check as it might not be fully correct. And actually NiBiTor is designed to extract the BIOS from a graphics card, while your video BIOS actually resides normally within the main BIOS of the laptop since it is a single chip that controls both. Have you tried to backup the video BIOS using GPU-Z as well?
Secondly before we can actually add the support for any graphics card we need to have a valid and correct BIOS so we can analyze the structure and ad the needfull code to recognize the BIOS and to correctly interprete the different parameters that are in the BIOS such as clock speeds, voltages, memory timings, etc. That alone takes a lot of effort and coding. And how did actually dump the BIOS using PowerStrip, I didn't know it had such a function?

I got PowerStrip mixed up with GPU-Z and the BIOS you have is actually a GPU-Z extraction. I extracted it a long time ago, and mistakenly recalled that it was from PowerStrip, which it most definitely is not. I have to apologize for misleading anybody on this. I've not had any trouble loading the BIOS into NiBiTor using a GeForce 7 series profile. But you can verify that for yourself, since you have the image.
I have also successfully modified the 3D clock rates of this BIOS from 425MHz to 530MHz using NiBiTor, and then saved the modified BIOS. I have not tried to flash it though, figuring I would wait for you to call this BIOS natively supported before I do that.

Indeed I wouldn't try to flash it as you should know that unless the BIOS is fully supported, such as natively supported it might not be the actual clock rate you are changing, so on that aspect I wouldn't have even tried to make any modifications. Well we will look at the BIOS and see to add the support, though it won't be before NiBiTor v4.9. Just so you know, since the next version is already finished and ready to be released as soon as the fund raising reaches its goal more or less.

Re:NVIDIA BIOS Editor (NiBiTor) v4.7 software and got feedback? - 2009/01/01 19:37Just a reminder, if you happen to have a BIOS of a graphics card that is not yet supported by NiBiTor currently please provide the original BIOS on this thread and tell us which card it is exactly with as much details. These will then be taken into account for NiBiTor v5.0 since the two other versions have already been finalized. But if we have those we will see to make sure those are included in the version that is currently in the works. And yes donations will help to make the new versions faster available.

Re:NVIDIA BIOS Editor (NiBiTor) v4.7 software and got feedback? - 2009/01/02 04:39Hi, I have spotted a couple of things that you might not have noticed. That is that nvFlash does not seem to agree with the device ID and board ID I modified via NiBiTor. I tried changing from one device to another but upon flashing the changes did not apply. I found a couple of BIOS for devices 0611 and 0614 that had the same version and were almost identical BIOS images
There seems to be a checksum at 0x005D and there is another byte at 0x006B that I you might also want to check. If you try to change device ID then you also have to change these values, otherwise device ID will not change upon flashing. And also the board ID is not being properly identified, it seems to be at 3 bytes before the second BIOS date.

Well, as long as NiBiTor is just editing the BIOS, I didn't see any harm in making changes. I figure as long as I don't flash that BIOS to the system, then it's okay. I did learn that NiBiTor v4.7 does save the image with no errors, that to me was significant. There is something else you should know though. NiBiTor is correctly correlating with what NVIDIA system tools is showing as far as the default clock rates. Meaning the GPU clock rate as 425MHz default.
Well we will look at the BIOS and see to add the support, though it won't be before NiBiTor v4.9. Just so you know, since the next version is already finished and ready to be released as soon as the fund raising reaches its goal more or less. I'll try to make another money dump soon, but damn aren't there more than three contributors out of all these leeches? Jeez. But yeah, you've got my support for life. I really like that ChipIn widget, cause it gives you a real good idea of where you are at and what's going on, and most importantly sets a goal to shoot for, which by the way I'm sure is extremely conservative based on the amount of work that you have to have put in this software already.

Thanks for letting us know and that has been noted down, in fact that is on the to do list for an upcoming version. Meaning that for now we can't include it in NiBiTor v4.8 or even v4.9 as these are already finished but will be taken up for the version after that. Did you haveany other input or even features or parameters you have noticed that are in the BIOS but not yet supported in NiBiTor? Cause now is the right time to let us know.
